CULTIVATOR ATTACHMENT.

Application filed October 12, 1906; Serial No. 338,681.

Specification of Letters Patent.

Patented.Dec.25, 1906.

- To all whom it may concern:

Be it known that 1, WILLIAM E. WRIGHT, a citizen of the United States,residing at May,

in the county of Brown and State of Texas,

have invented a new and useful Cultivator Attachment, of which thefollowing is a specification.

This invention relates to harrow attachments for cultivators; and itsobject is to provide a simple and inexpensive device of this characterwhich is of durable construction and which is adapted to be substitutedfor the shovels of a cultivator, so that said cultivatorcan be easilyconverted into a harrow. By substituting this attachment for the shovelof a riding-cultivator the harrow can be used for working the soil atopposite sides of rows, thereby rendering it particularly serviceable incultivating small growths and suitable for working out corn, cotton, &c.for the first time.

With the above and other objects in view the invention consists ofcertain novel features of construction and comblnatlons of parts, whichwill be hereinafter more fully described, and pointed out in the claims.

. In the accompanying drawings is shown the preferred form of theinvention.

In said drawings, Figure 1 is a perspective view of a portion of acultivator having the improved attachment applied thereto, saidattachment being slightly exaggerated as compared to thecultivator-stocks; and Fig.

2 is a view, partly in plan and partly in section, of the attachment.

Referring to the figures by characters of reference, 1 1 are stocks of acultivator, and to eachof these stocks is secured an attach mentconstituting the present invention, saidattachment being adapted to beused in place of the cultivator-shovels, which are ordinarily secured tothe stocks. The attachment comprises a metallic strip 2 of any suitableproportions, having an 'oflset intermediate portion 3 bent alongdiagonal lines, as shown at 4, so that said offset portion is disposedat an incline to the planes occupied by the edges of the strip. Thisoffset portion has an opening 5 for the reception of the bolt 6, wherebythe same may be readily fastened to the stock. Arranged within the strip2 at desired intervals are pairs of parallel slits 7, and those portionsof thestrip between the slits are struck outward to form holding-straps8. Teeth 9 are adapted to be driven between these straps 8 and thestrips and are held in placeby frictional contact therewith. I Theseteeth are preferably in the form of elongated cylindrical prongs havingtheir lower ends pointed.

Im ortance is attached to the fact that the attac ment outside of theteethis formed in but a single piece and that therefore there are noparts to become detached and lost. By formin the strip of spring metalthe straps 8 W111 .exert a clamping action upon the teeth, so that thesame will be able to resist considerable strain without becomingdetached. It will of course be understood that this attachment can beused upon a singleshovelcultivator or u on a cultivator employing a.plurality of s ovels, oneof theattachments being adapted to besubstituted for each shovel. By substituting the attachment for theshovels of a two-row cultivator two rows can be worked simultaneously.The attachment is especially desirable in view of its simple andinexpensive construction and its durability. By having the inclinedintermediate offset portion the harrow attachment can be fastened to theusual in: clined stock and the teeth will be maintained at a roper angleto the ground.

- W at is claimed is 1. A harrowattachment for cultivators comprising anelongated strip having integral longitudinally-extending straps strucktherefrom, and teeth interposedbetween and I held by the straps and thestrip.

2. A harrow attachment for cultivators comprising an elongated striphaving an offset -mtermediate portion, longitudinally-extending strapsintegral .with and struck from the strip, and teeth interposed betweenand held in position by the straps and strip.

3. A harrow attachment for cultivators comprising an elongated striphaving an inclined intermediate offset portion, longitudinally-extendingstraps integral with and struck from the strip, and teeth inter osedbetween the strips and strap and held in position by frictional contacttherewith.

4. A harrow attachment for cultivators comprising an elongated strip ofresilient material having aninclined offset intermediate portion, andlongitudinally-extending straps integral with and struck from the stripat opposite sides of the intermediate portion, and teeth disposedbetween and clamped in position by the strip and straps.

5. The combination with a cultivatorstock; of a harrowattachmentcomprising an elongated strip having an intermediate inmy own I havehereto afiixed my signature clined offset portion, means for securinisaid in the presence of two Witnesses.
